The transpiration method was used to measure the density of melted borax vapours at 900 to 1115 °C in nitrogen atmosphere and in nitrogen-water vapour mixtures. The results imply a relatively small effect of water vapour on the density of borate vapours and are indicative of quasi-congruent vaporization resulting from the reaction of the melt with water vapour. |
